Plate Tectonics: stress, tension, faults
The first column is the compositional layers,distinguished by the ingredients that make each layer.
The second column is the physical layers, distinguished by the solidity and movement of each layer
is the theory that continents can drift apart from one another and have done so in the past
is the process by which new oceanic lithosphere is created as older materials are pulled away
the theory that the Earth's lithosphere is divided into tectonic plates that move around on top of the asthenosphere
When two tectonic plates push into one another, the boundary where they meet
The boundary between two tectonic plates that are moving away from each other.
The region where oceanic plates sink down into the asthenosphere.
the boundary between two tectonic plates that are sliding past each other horizontally
the amount of force per unit area that is put on a given material
the type of stress that occurs when an object is squeezed as when two techtonic plates collide.
Stress that occurs when forces act to stretch an object.
Occurs when rock layers bend due to the stress in the Earth's crust.
The surface along which rocks break and slide past each other.
a fault in which the hanging wall moves down relative to the footwall
A fault in which the hanging wall moves upward relative to the footwall.
occurs when opposing forces cause rock to break and move horizontally
